As in real life, chickens are classified as birds, therefore, the player can control a chicken whilst eating a Peyote Plant, however, unlike all the other birds, they can't fly or even jump, making it hard or even impossible to leave some areas such as the Vinewood hotel or an island without using mods to change the player's location.

Behaviour

When approached, chickens will run away, but if the player remains still, they will gradually come back to where they were.
